C# How to use a while loop with a percentage from a TextBox

I have been searching of a way to do this little exercise from my programming book, but I'm not able to think how to do this.

Here is what I have so far:

private void btnDisplay_Click(object sender, EventArgs e)

{

    int numOrg = Convert.ToInt32(txtNumOrg.Text); 

    double numberToConvert = Convert.ToDouble(txtDailyIncrease.Text); // percent



    double convertToDecimal = (numberToConvert / 100);



    while (numOrg <= 10)

    {

        lstDisplay.Items.Add(numOrg + "   " + convertToDecimal  );  

        numOrg++;

    }

}

For the values I am using: numOrg is 2 and numberToConvert is 30%.

The expected output should be: 2.6000, 3.3800, 4.3940, etc.

I just want to add an increase to my number each day. I definitely over complicated this simple task, but I've put 7 hours into this already and I'm not getting anywhere so I'm hoping someone can help me see this problem a little more clearly. Thanks in advance guys!

Do you want to calculate percentage ? Please clarify your problem clearly..

I want to add 30% increase to my number each day. For example, the first day is 2 so, 2.6... the next day is 3 so the old value (2.6 + 30%)

At the moment you're only dividing the entered percentage by 100 and adding it to lstDisplay multiple times. You need to do some calculation with that value (I assume you have some basic knowledge of maths...)

Suppose you enter 100 in numOrg and 10 in DailyIncrease. Are you expecting increament of numOrg by 10 % should add in lstDisplay? So in lstDisplay110 should be added. Is this your requirement?

– Yogesh Patel
Nov 23 '18 at 12:39

Yes, exactly, and then the next number would be 101 with the 10% DailyIncrease so on and so forth

Please check this code:

static void Main(string args)

    {

        var numOrg = 2;

        var percentage = 0.3;

        var result = (double)numOrg;

        while (numOrg <= 10)

        {

            result += percentage * result;

            Console.WriteLine($"{numOrg}: {result}");

            numOrg++;

        }



        Console.ReadKey();

    }

It generates expected result:

2: 2,6

3: 3,38

4: 4,394

5: 5,7122

6: 7,42586

7: 9,653618

8: 12,5497034

9: 16,31461442

10: 21,208998746

I dont't know what exact logic is behind your code. Maybe you should loop from 1 to stop value and use numOrg only as value for calculations.
